FURNACE.

Application filed December 13, 1924. Serial No. 755,698.

The invention relates to a furnace as described in the present specification and illiuitrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel features of construction pointed out broadly and specifically in the claims for novelty following a description containing an explanation in detail of an acceptable form of the invention.

The objects of the invention are to con.- serve the heat generated by directing the flow of the heating gases in a natural course, so that the heat is absorbed in passage into the metal having a maximum heating surface and a free outlet afforded for the waste and cooler gases; to reduce the cost of pro duction and facilitate the operations of the foundry; to enjoy all the advantages of the sectional type of furnace both in the manufacture and the installation; to eliminate the carbonization in the heat radiating elements; to increase the life of the furnace and insure comforts to those heating their houses and buildings by hot air; and generally to provide efficiency at a minimum consumption of fuel in a durable and serviceable furnace.

In the drawings, Figure l is a perspective view of the furnace showing one side wall removed.

Figure 2 is a perspective view showing from the front the interior construction.

Figure 3 is a perspective view, showing from the rear the interior construction.

Figure 4: is a vertical sectional view through one of the heat elements, fire pot and base.

Like numerals of reference indicate corresponding parts in the various figur s.

Referring to the drawings, the radiator sections 5 are formed of inverted vertical V-shaped fines, each in two pieces secured together by bolts 8 one side 9 being longer than the other side 10 and communicating through the passage 11 between the walls 1.2 and upper walls.

The firepot 13 in size is made to meet the requirements in regards to the number of sections 5 to be used and is formed of a bowl l-i closed in by the top 15 set thereon and secured by the flange 16. The firepot l3 communicates through the radiator sections 5 with a longitudinal flue 19 formed of the upper and lower sections 18 and 17,

the former having communicating openings to the vertical flues 10 and secured thereto and the latter forming part with the top 15 and the vertical flues 10 fit over the openings 20. The sections 5 are spaced by the bars 21 engaging the central pins 22, while the furnace front 23 abuts the front sect-ion and the back 24 the rear section, thereby firmly holding the sections in position.

The back wall 24 and side walls 25 and 26 are formed in vertical sections and fit together with overlapping flanges and one of said vertical sections has the water pan 27 extending from the outside through the wall to the inside.

The said vertical sections are formed of outer and inner walls 28 and 29 spaced to form cold air passages and having outlets 30 at the lower end thereof through the inner walls 29; the said passages registering with passages in the furnace cap 31 that con nects with the customary cold air channels.

The firepot bowl 14 is mounted on the base 32, which is formed with lugs 33 for the walls and an outer retaining flange 34 completely there-around and carrying a support 35 thereon for the rear end of the firepot. in the operation of the furnace the usual fuel for this type is wood and the heating is by warm air descending from the furnace enclosure through the passage provided in the cap and through the usual channels to the rooms to be heated.

The heating gases from the firepot enter the long legs of the heat sections and rise to the body portion where they hang until the heat is absorbed by the metal wall of the body and radiated therefrom into the enclosure rising quickly through the cap. There is no descent of the heating gases, so long as they remain hot as the tendency to rise is inherent in the lighter heated air, consequently the flow down the short legs 10 will always be the waste portion of the gases quite cool and of no service for heat and this flow will enter the flue and be dissipated in atmosphere through the usual piping and chimneys.

lVhat I claim is 1. In a furnace, a plurality of vertical fiues in inverted U-shape having inlets at the lower end on the one side and outlets at the other side, a firepot and a closure mounted thereon having inlets to said flue inlets and carrying a flue extending therealong and communicating with said outlets and a casing enclosing said parts and affording a hot air furnace.

2. In a furnace. a plurality of v *rtical flues'in inverted ll-shape having inlets at the lower end on the one side and outlets at the other side, a lirepot and a closure mounted thereon having inlets to said tine inlets and carrying a ilne extending therealong and communicating with said outlets and a casing enclosing said parts and ali'ording a hot air furnace and having a firebox opening in the front thereof.

3. In a furnace. a plurality of vertical tines in inverted "L -shape havinginlets at the lower end on the one side and outlets at the other side. each of said inverted vertical tines formed of two flanged pieces bolted together, a firepot and a closure mounted thereon having inlets to said flue inlets and carrying a flue extending there along and coinn'nuiicating with said outlets and a casing enclosing said parts and affording a hot air furnace.

l. In a furnace, a plurality of vertical flues in inverted U-shape having inlets at the lOWOl' end on the one side and outlets at the other Side, each of said inverted vertical flues formed of tvvo pieces secured together and elliptical in cross section at their lOWCl ends and open at the bottom. a lirepot and a closure mounted thereon having inlets to said flue inlets and carrying a flue extending therealong and coinniunicating with said outlets and a casing enclosing said parts and affording a hot air furnace.

In a furnace, a plurality of vertical flues in inverted U-shape having inlets atthe lovver end on the one side and outlets at the other side and having rounded top distanced by spacing bars, a firepot and a closure mounted thereon, having inlets to said tine inlets and carrying a fine extending there-along and communicating with said outlets and a casing enclosing said parts and affording a hot air furnace.

(3. In a furnace. a. plurality (if-vertical fines in inverted U-sliape having inlets at the l()-.\ r end on the one side and outlets at the other side, a tirepot and a closure mounted thereon having inlet to said flue inlets and carrying a longitudinal chimney iiue communicating with said vertical flue outlets and a casing formed of vertical sections having cold air passages tliereivithin enclosing said parts and affording a hot air furnace.

7. in a furnace, a phrality of vertical lines in inverted U-shape having inlets at one lower end on the one side and outlets at the other side, a firepot and a closure inounted thereon having inlets to said flue inlets and carrying a fine extending therealong and communicating with said outlets and a casing formed of vertical sections having outer and inner Walls spaced to form cold air passages and having outlets at the lOWQl end thereof through said inner Walls, said casing enclosing said parts and affording a hot air furnace.
